Metabo H 16-500 Operating Instructions 2 - Page 11

ENGLISH ENG Press the buttons (6) to set the temperature. Briefly press the "+" /"-" buttons to increase or lower the set value in 10° steps. Press the buttons longer to change the value faster. Notes: Triangles are displayed when the desired temperature is being set. If the desired temperature is set, the blower (depending on the selected speed/air volume) needs a few seconds to reach the set value. The triangles flash during this period. The actual temperature is measured at the nozzle outlet. The triangles disappear when the desired temperature has been reached. When the hot air gun is switched off, the last value set is retained. Setting air volume: Press the buttons (7) to set the air volume or the fan speed. Program operation: Four programs for the most frequent types of work are set in the factory. Press the "P" button for program operation. A for program 1 appears in the display. Press the program button again to reach the programs , and . Press the button again to return to normal operation. Program 1: Forming plastic pipes Program 2: Welding plastic pipes Program 3: Removing paint Program 4: Soft soldering (For technical data, see chapter 12) Changing programs and saving: The values in the four programs can be changed and saved. To do this, first press the program button "P" until the program to be changed is displayed. Set the desired air volume and temperature. Then push the save button (10) until the symbol in the display disappears (approx. 5 seconds). The entered values are now saved in the program. Note: - To return from program operation to the normal function, press the program button (8) until the program symbol in the display (9) has disappeared. - The factory settings of the programs are listed in chapter12. 6.4 Stationary operation If you wish to use the hot air gun as a stationary tool, ensure that it is placed on a safe, anti-slip and clean base. To use the hot air gun in stationary operation, place it on the anti-slip bases (5). 7 Servicing The air inlet (3) with grid must be free of foreign bodies. Clean the air inlet (3) if necessary. 8 Troubleshooting Thermal protection The tools are equipped with 2-stage thermal protection: 1. * A thermo switch switches off the heater in case of excessive interference in the air outlet of the blow-out opening (heat accumulation). However, the blower continues running. When the blow-out opening is free again, the heater cuts in again automatically after a short while. The thermo switch can also trip after the tool is switched off. In this case, after the tool is switched on again it takes longer than usual until the temperature at the blow-out opening is reached. * does not apply to HE 20-600, H 16-500 2. The thermal fuse switches the tool off completely in the event of overloading. Short-term voltage drops Switching on the machine reduces the voltage briefly. Unfavourable mains power conditions may have a detrimental effect on other machines. Network impedances less than 0.4 ohms should not cause malfunctions. 9 Accessories Use only genuine Metabo accessories. If you need any accessories, check with your dealer. For dealers to select the correct accessory, they need to know the exact model designation of your power tool. For possible accessories, refer to the illustrations on page 3.
